Irma/5v Patented Oct. 22, 1935 UNITED STATES ATE'i Fries 3 Claims.

wrenches and the main object is to provide a wrench in a simple andpractical form in which the jaws are rotatably mounted on the handle foradjustment to various angular relationships whereby the wrenching ortwisting action on the work may be applied by either swinging the handlelaterally or turning it on its axis as best suited to the work.

Another object is to provide a wrench suitable for use inside a pipe orother work as well as outside for nuts, bolts and the like.

A further object is to provide a wrench of this kind comprising ahandle, a serrated inner jaw and an arcuate outer jaw hinged thereto andserrated both inside and out for gripping work either interiorly orexteriorly, the said inner jaw having a shaft journaled through thehandle at one end and locked against axial displacement therein andcarrying a serrated head opposite the jaw assembly.

With these and other objects in view the invention resides in the novelconstruction and arrangement of parts as hereinafter fully set forth andclaimed, reference being had to the accompanying drawing wherein:

Figure 1 is a side view of the wrench partly in section to show theinterior arrangement.

Figure 2 is a fragmental elevation showing the jaws turned to anotherposition relative to the handle and gripping a nut for turning the same.

Figure 3 is an end view showing the jaws arranged for gripping theinside of a pipe which is indicated in section.

Referring now with more particularity to the drawing my wrench comprisesa handle I having a sleeve 2 at one end through which a cross rod 3 'isslidably mounted in well known manner for con- Venience in turning thehandle and having a diametrically extended bearing aperture 4 near itsother end communicating with an axially and inewardly directed springsocket 5.

An inner jaw 6 having an arcuate and serrated gripping face 1 hasa studor shank 8 extended from its opposite and flat face 9 and journaledfreely through the aperture 4 in the handle. At the opposite end of theshank 8 a head I is formed either integrally or separately and fastenedin place and this head has an arcuate and serrated M in the springsocket as shown. This arrangement allows the shank 8 and the jaw 6 toturn freely but frictionally holds the parts in any adjusted position.

An arcuate outer jaw l is provided and is ser- 5 rated on both its innerand outer faces 86 and I1 and at one end is forked or cut away toprovide spaced bearing ears l8 which are adapted to receive and embracethe inner jaw 6 near one end thereof. This end of the jaw 6 is roundedas 10 shown at H! and the outer jaw is hinged in place thereon by ahinge pin or rivet 20 passed through aligned apertures 2| in the ears l8and the jaw 6.

The outer jaw I5 may thus be swung toward or away fro-m the inner jaw 6so as to accommodate a nut or other work of most any size as indicatedat A in Figure 2. The nut thus placed between the jaws will be grippedby these jaws as the handle is pulled or swung laterally in thedirection indicated by the arrow B or will be likewise gripped andturned by simply rotating the handle I on its axis when it is swung tothe position relative to the jaw as shown in Figure l. The gripping ofthe nut by the jaws is' caused by the eccentric location of the hinge ofthe outer jaw as the handie is turned as will be readily evident. Ofcourse, the serrations on the jaws enable them to grip a pipe or roundobject as well as the nut shown.

For use inside a pipe or spud as indicated at C in Figure 3, the outerjaw 15 is swung over against the inner jaw 6 presenting the serratedouter face of the former for engagement with therounded inner peripheryof the pipe. The rounded and serrated face i l of the shank head I!)then engages the pipe interiorly and the pipe may be gripped and turnedby turning the handle I which in this case is swung so as to enter upinto the pipe as shown. The hinge point of the outer jaw is now solocated that as the wrench is turned as indicated by the arrow D thisjaw is faced outward and the jaws wedge against the pipe.

The wrench is thus seen to lend itself to use both interiorly andexteriorly of. the work and due to the swiveling of the jaws on thehandle the tool may be used in many locations where it would beimpossible to swing the handle but where the handle may be turned on itsaxis.

While I have herein set forth a certain preferred embodiment of myinvention, it is understood that I may vary from the same in minorstructural details, so as best to construct a practical device for thepurpose intended, not departing from the spirit of the invention andWithin the scope of the appended claims.

I claim: 7

1. In a device of the kind described, a handle having adiametricallyextended aperture near one end,-a shank journaled through the said'bearing aperture, a jaw assembly mounted on one end of the shank andincluding a hinged arcuate jaw serrated on its inner and outer roundedfaces, and a head on the other end of the shank and having a rounded andserrated outer face.

2. In a device of the kind described, a handle having a. diametricallyextended bearing aperture adjacent one end" and a spring socket enteringthe said aperture, a shank journaled through the said aperture andhaving a peripheral groove in alignment with the said spring socket, aball in the socket and a spring in the socket urging the ball into thesaid groove, an inner jaw formed on one end of the shank and a headformed on the other, the said inner jaw and head having the1r outerfaces rounded and serrated, and an arcuate outer jaw hinged to one endof the inner jaw and serrated on both its inner and outer concave andconvex faces.

3. In a device of the kind described, a handle having a diametricallyextended aperture adjacent one end, a shank journaled through theaperture, a rounded and serrated inner jaw formed on one end of theshank, a rounded and serrated head formed on the other end of the shank,and an arcuate outer jaw hinged at one end to the inner jaw on theshank, the said outer jaw being ser-' rated on both its inner and outerfaces.
